U-PHOLSTERY-SPRING.

SPECIFICATION forming part of Letters Patent No. 536,123, dated March19,- 1895 Application filed October 10, 1894. Serial No. 525,4,87- (Nomodel.)

' To all whom it may concern.-

Be it known that I, ALBERT E. BEALL, a citizen of the United States,residing at Hubbard, in the county of Hardin and State of Iowa, haveinvented a new and useful Upholstery- Spring, of which the following isa specification.

Thisinvention relates to upholstery springs, and it has for its objectto provide a new and adapted for use as a bed spring to provide a springbed, reversible in character, while at the same time providing a lightand strong bed having all the necessary spring requirements, and yet soconstructed as to retain its shape under all conditions.

The invention is particularly designed as an improvement on my formerpatent, No. 514,898.

With these and'other objects in view, which will readily appear as thenature of the invention is better understood, the same consists in thenovel construction, combination, and arrangement of parts hereinaftermore fully described, illustrated, and claimed.

In the drawings:Figure l is a plan view of a portion of a spring bedformed with the herein described spring. Fig. 2 is a side elevation ofthe same. Fig. 3 is a detail in perspective of one of the springs.

Referring to the accompanying drawings: 1 designates an upholstery orbed spring shaped from a single continuous length of spring wire, andthe length of wire forming the spring 1, is bent to form the spacedduplicate parallel V -shaped spring portions 2,

7 that are vertically disposed and are provided at their intermediateapiece, and at the extremities of their arms with the spring coils 3 -4.This construction is substantially the same as shown in my former patenthereinbefore referred to, but in the present invention the oppositeportions of the wire forming the spring are extended from the upper andlower pairs of terminal spring coils 4, beyond the coil apices 3, of theV-shaped spring portions 2, to form the upper and lower horizontal U-shaped portions 5, that are of the same size and shape and thereforemake the spring reversible in character, so that weight may be placedthereon from either the upper or lower side thereof.

useful spring of this character'particularly By reasonof theconstruction of spring described, having duplicate upper and lowerhorizontal portions and duplicate parallel V- shaped spring portions, itwill be obvious that the spring will have considerable strength,

while at the same time yielding very readily to weight placed thereon soas to form an easy and comfortable spring for all upholstery purposes.

In using the spring, to provide a complete spring bed, the use of slatsis entirely avoided on account of the wide upper and lower horizontalU-shaped portions 5, either of which portions, according to the positionconnected by intermediate connecting wires 6, which together with theU-shaped portions of the interlocked springs, form a fiat surface forthe bed bottom composed of the connected springs. V I

While the construction of spring described, is well adapted to securetheresults noted, an intermediate horizontal spring coil brace 7, isarranged between the parallel V-shaped spring portions 2, of eachspring, and is secured at its opposite ends in the intermediate apexcoils 3, of said spring portions, and the said spring coil braceproduces a flexible coupling between the opposite side portions of thespring to prevent any side motion thereof and to provide for keeping allthe parts of the spring relatively position ed or in their proper shape.

Changes in the form, proportion and the minor details of constructionmay be resorted to without departing from the principle or sacrificingany of the advantages of this invent-ion, and at this point it is to benoted that when the herein described spring is employed in the make-upof a spring, bed bottom, as illustrated in Fig. 1 of the drawings, thehorizontal spring coils braces 7, are made continuous and extend theentire width of the bed bottom through the aligned central or apex coils3, of the transverse series of springs.

Having thus described theinvention, what is claimed, and desired to besecured by Letof the transverse series of V-shaped spring to tersPatent, is portions, substantially as set forth.

In a spring bed bottom, the combination of In testimony that I claim theforegoing as a regularly arranged series of springs, each my own I havehereto aifixed my signature in 5 having a pair of parallel V-shapedportions the presence of two witnesses.
